1.Which diagram shows a land breeze? 2.Which diagram shows a sea breeze? AB Lesson Essential Question: What makes the wind blow locally and globally?

Go over bellringer Make sure Winds Frayer diagram is complete Finish notes on Local Winds/Land and Sea Breezes Take notes on Global Winds Label diagram with convection currents Label 5 types of global winds Describe each type of global wind Complete the “What is Wind” graphic organizer

Definition: Caused By: Described by and measured with: Sketch: Wind-chill Factor – The name of the wind tells you where the wind is _____________________. Write an example: The horizontal movement of air from an area of high pressure to an area of low pressure. Differences in air pressure and an unequal heating of the atmosphere. Described by speed and direction. Measured with: Anemometer – wind speed Wind vane – wind direction The increased cooling wind can cause. coming from A south wind comes from the south

Why Does Land Heat Up and Cool Down Faster? A solid has molecules that are closer together than a liquid. This allows for better heat transfer capabilities. Think of a pool table with all the balls tightly in a rack. When you hit the balls with the cue ball, they scatter easily. If they were not so tightly packed, they would not scatter as well. Water has a higher specific heat capacity than that of land. That means it requires more energy to heat water to the same temperature you are heating the land. Water retains heat more than land which is unable to retain heat for as long however it absorbs heat well.

Local breezes are winds that blow over ____________________. They are caused by the ____________________ of Earth’s surface within a small area. Two types of local breezes are: ____________ breezes and ___________ breezes. short distances unequal heating land sea

9 Winds What type of breeze is occurring?

10 Winds What type of breeze is occurring?

Angle of the Sun’s Rays Energy from the sun strikes Earth most directly near the equator. Near the poles, the same amount of energy is spread out over a larger area.

Global Wind Belts Global winds are winds that blow over ___________ _________. They are caused by the ___________ _________ of Earth’s surface within a large area. large distances unequal heating

Global Wind Belts Produced by the movement of air between the equator and the poles. Global Winds Video ClipGlobal Winds Video Clip

Jet Streams The jet streams are high-speed ( km/hr) bands of winds occurring at the top of the troposphere.

Coriolis Effect The ________Effect is the name given to the concept that the Earth’s ________makes the winds ________. It is important in causing the motion of the global winds. The Coriolis Effect occurs on Earth and other planets because the planets rotate. Coriolis rotation curve The Coriolis Force

Coriolis Effect As Earth rotates, the Coriolis effect turns winds in the Northern Hemisphere toward the right. X Even though this arrow appears to be pointing to the left, the wind is curving to the right from the direction it is blowing (marked by the ‘X’)

Causes Effects : _______ air expands, becomes less ________, and ________. ___________ heating of the land and atmosphere and differences in _________________. Dense cold air has a higher pressure than less dense warm air. _______ blows from areas of ________ pressure to areas of _______ pressure. _______ air contracts, becomes more ________, and _______.

Thursday, July 02, 2015 Complete the “Winds Homework” w/s! Quiz tomorrow on Energy in Earth’s Atmosphere

Students are divided into teams of four to five. The first student in each team starts with a blank piece of paper and writes one summary sentence, then passes it to the next teammate. That student adds a sentence, passes on, etc., until the whole team has added or until the number of required sentences is on the paper.

1.Write a riddle describing a concept learned with wind: EX: I spin round and round, Measuring wind speed, for that I’m proud. EX: Be careful not to lose for kite, For, if you let go, my wind currents will causes your precious toy to curve to the right.
